摘要:

Thirty‐one silver coins of the Hellenistic period were examined by the particle induced X‐ray emission (PIXE) method, and the results incorporated into a wider study of the coins. Some tentative conclusions reached in the study are mentioned, together with an outline of the PIXE method. A number of patterns emerged in the results, the most important being an apparent deterioration in silver content among the later Seleucid and Ptolemaic issues; some high concentrations of particular elements were also no

摘要:

Results suggest that ESR studies of Mn+2in marble can provide an excellent discriminator for the determination of marble provenance. In comparison with other methods of quantitative analysis for manganese such as AA or NAA, the ESR method determines only Mn+2rather than total Mn, is inexpensive and rapid with no chemical preparation required, and does not consume the sample.

摘要:

Previously 245 Augustan quadrantes were analysed for seven elements. Physical measurements comprised the weight, maximum thickness and diameter, minimum diameter, and die orientation for each coin. Both chemical and physical data were subjected to discriminant analysis, and centroids in multi‐dimensional space were obtained for each of the four groups. A tetrahedron was drawn using the four centroids; each corner was separated from the other groups by a Mahalanobis distance. We hypothesize that the most probable relative chronology comprises the smallest sum of Mahalanobis distances connecting all four points. The most probable chronology for the quadrantes is c. 8, 9, 5, and 4 B.
